Through Hole Resistors

Through-hole resistors, also known as leaded resistors, are the oldest type of resistors in use. The term through-hole refers to the mounting method, in which leads are inserted into holes in circuit boards — physical components that make up an electronic system — and then soldered into place. The CMF55442K00FHEB is a through-hole resistor designed for transformer taps and other signal discrimination applications.

Applications

The CMF55442K00FHEB through-hole resistor features a stainless steel casing, which is highly resistant to mechanical and environmental wear and corrosion. This robust casing makes the CMF55442K00FHEB ideal for use in harsh industrial settings, such as in factory automation, machine vision systems, and remote industrial controls or data acquisition systems. The device is also suitable for medical and laboratory-instrumentation circuitry. Additionally, the device also finds use in certain automotive applications.

Working Principle

The working principle of a through-hole resistor is relatively straightforward. An electrical signal is applied to one lead of the resistor and the current passes through its body, eventually reaching the other lead. The current passes through the Central Leg and then flows through an external circuit. This flow is restricted by the resistor’s body and the resistance that is present, resulting in reduced current. Since the exact amount of resistance applied in a resistor can differ based on the material used, different types of resistors are made available in a wide variety of resistances.

Benefits

Through-hole resistors offer reliable performance and cost-effectiveness, making them a popular choice for many applications. The device’s casing is also highly resistant to environmental and mechanical stress such as vibration, shock, and abrasion, making it well-suited for use in harsh industrial settings. Additionally, the device’s multiple leads allow for easy assembly and soldering, as well as increased heat dissipation.

Conclusion

The CMF55442K00FHEB is a through-hole resistor designed for transformer taps and other signal discrimination applications. With its stainless steel casing and multiple leads, the device is highly resistant to environmental and mechanical stress and is well-suited for use in harsh industrial settings. Additionally, the device also offers cost-effectiveness and easy assembly, making it a popular choice for many applications.
